Radical fluoroalkylation reactions of (hetero)arenes and sulfides under red light photocatalysis

Abstract

Fluoroalkylation reactions of (hetero)aromatics have been accomplished through the low-power illumination from red LEDs (λ_max = 635 nm) of commercially available perfluoroalkyl iodides R_F-I and phthalocyanine zinc salt as photocatalyst in MeCN : DMF solvent mixture. This methodology has been extended to the perfluorobutylation of sulfides. As far as we are concerned, this is the first report on a perfluoroalkylation reaction of (hetero)aromatics and sulfides under red-light photocatalysis.
